Embodiment 1

[0046] like figure 1 As shown in the figure, this embodiment provides a construction method for a spherical warehouse, which includes: the step of constructing a thermal insulation layer; after the step of constructing the thermal insulation layer, several steel bar pendants are embedded on the inner surface of the thermal insulation layer, The steel bar pendant is fixedly connected.

[0047] In detail, as figure 2 As shown in the figure, after the steps of foundation construction and preparation, the steps of laying and installing the membrane body, and the step of constructing the thermal insulation layer, the steps include: burying several steel bar pendants on the inner surface of the thermal insulation layer; and spraying concrete on the side of the reticulated steel bar away from the thermal insulation layer.

[0048] In the construction method of the spherical warehouse provided in this embodiment, by using the reinforcing bar pendant to fix the reinforcing bars, the...

Embodiment 2

[0050] further, as figure 2 As shown, this embodiment is based on the above-mentioned embodiment 1, before the inner surface of the thermal insulation layer is embedded with the steel bar pendant, the position where the steel bar pendant is embedded in the heat preservation layer is marked, and the steel bar pendant is installed at the marked position; image 3 As shown, in this embodiment, the steps of marking the position of the embedded thermal insulation layer of the steel bar pendant include: (1) marking the bottom layer at a certain distance between the thermal insulation layer and the top surface of the foundation ring wall; (2) marking the bottom layer on the silo body A rope-shaped measuring device extending to the bottom surface of the silo body is fixed at the top center point of the silo body; (3) the rope-shaped measuring device is projected on the insulation layer at a certain distance in the vertical direction, and vertical marks are made in turn; and (4) the si...

Embodiment 3

[0053] further, as figure 2 As shown, on the basis of the above-mentioned Embodiment 1 or 2, after the step of burying the steel bar pendant on the inner surface of the thermal insulation layer, the present embodiment also includes spot checking the thickness of the thermal insulation layer and the anchoring force of the reinforcing bar pendant. In this embodiment, the evenly distributed vertical straight line spacing of the rebar pendants is 700mm, the horizontal straight line spacing is 500mm, and the distance between the bottom steel bar pendant and the top surface of the foundation ring wall is 200mm.

[0054] Spot check the coating thickness on site, and check the coating thickness with a blunt tip probe (the needle tip is blunt iron). At least 90% of the measuring points meet the minimum plane thickness requirements. No less than 15 points should be checked for adhesion strength. The inspection method is the same as that of the adhesion strength test method during test ...

Abstract

The invention provides a construction method for a spherical cabin. The construction method comprises the steps that a heat preservation layer is constructed; and after the heat preservation layer is constructed, a plurality of steel bar hanging pieces are embedded into the inner surface of the heat preservation layer, and net-shaped steel bars are fixedly connected with the steel bar hanging pieces. According to the construction method for the spherical cabin, the steel bars are fixed by the steel bar hanging pieces, so that a steel bar net-shaped structure and the heat preservation layer are pasted more closely, on the one hand, the using quantity of concrete filled between the steel bar net-shaped structure and the heat preservation layer is reduced so as to reduce materials, and on the other hand, a forced structure of the spherical cabin is more reasonable.

Description

technical field [0001] The invention relates to the field of storage bins, in particular to a construction method of a spherical bin. Background technique [0002] The spherical membrane thin-shell concrete storage silo is the ideal storage silo with the largest storage capacity per unit area. The advantage of the thin-shell structure is that the pressure can be evenly distributed to all parts of the object, reducing the pressure, so its structure Reasonable and high pressure capacity. [0003] The spherical silo in the prior art generally includes a ring beam foundation, a PVC air-mold waterproof layer formed by heat fusion welding of a PVC fabric, a polyurethane thermal insulation layer, a reinforced concrete layer and a reinforced mesh, the reinforced mesh is hemispherical, and The bottom steel bars are fixedly connected with the steel bars pre-buried at the bottom of the ring beam foundation, the PVC inflatable waterproof layer is covered on the upper surface of the rei...
